Log formatting

[1000TurquoisePogs]

Some ZSS logs now have message IDs
Yet, many don't
And none of them have timestamps.
This makes troubleshooting more difficult.
We've tried to implement the format in zowe/zac#90 multiple times and PRs have never finished.
Please lay out rules to follow with logs so that PRs on the subject will succeed.

Previous discussions said things like

• Don't log library code, use return codes instead
• Use a log formatting interface so that different users of our codebase can have formats other than the one above, though ZSS will be compiled to use the one above
• Logging changes added for ZSS should change ZIS. Maybe ZIS needs enhancement at the same time, or maybe certain area of the code shouldn't be touched?

And some thoughts

• If there are logs where they shouldnt be today, that's a separate problem from adding formatting. We don't need to put PRs on hold if we can move forward one step at a time.

debug-level tracing really should have logs pervasively, though info-level shouldnt appear in library code since library code should be using RC/RSN instead.

[1000TurquoisePogs]

timestamps must not break ZIS messages (it already has its own)
